error code and other symptoms- help?

[apmurphy]

so since i put my body kit on, (like 6 months ago?) my check engine light has been on and giving me code P0422- evap system small leak. a while back i removed and cleaned the egr and iac but no luck there. ive never checked the pcv, but i also don't know where to find it. haynes manual gave a description but no image so i was pretty confounded. the lines all seemed fine, but maybe i just need to replace the pcv or something small like that? oh- some other symptoms are shudder at takeoff and comming to a stop, as well as when letting off the gas after accelerating for a bit. i didnt know if that was just a busted motor mount or something though (similar thing happened 3 times in my old villager minivan). anyways, any ideas are appreciated.

The system for code P0442 is the evaporative system or fuel vapor system. A very small leak less than .040"... Since it happened just after the lift you need to look at the hose and clamps to the fuel filler neck. Also check the fitting to the front and goes to the canister purge valve.

Here is a pic of the Filler neck and clamps. Make sure the tube is clean and clamps are tight.
